I know that FIRE (generally speaking) is about saving the monthly income and investing it.
The first part is easy to me - being a frugal person and a minimalist, I manage to save about 50% of my monthly income (after taxes).
What does concern me a is the investing part. I read JL Collin's Stock Series and got the right mindset of "not panicking when the market goes down", but the stock market still seems like a massive inconvenience to me.
Thus, I wonder - is it possible to retire early without investing in stocks, when not having any other source of income apart from a job? (no real estate to rent or sell either) I know it is a bit of a general question, for it involves many day to day aspects, but I'm trying to figure out how vital investing is for FI.
My first point of concern is that, living outside of the US and Europe, investing comes with a limited choice of stocks, high fees, and additional taxes, turning index funds like VTI to be not cheap.
My second, and way bigger concern: I like to be in control with the many aspects of my life, money is one of them. The stock market is a chaotic and unpredictable, thus makes me worried and uncomfortable, despite knowing that the market always goes up, as Jim likes to repeat.
